“…Unbalanced physeal growth between the radius and ulna can result in forearm bowing, relative shortening of radius or ulna, carpal instability, and radial head dislocation with subsequent limitation of forearm rotation [ 1 , 4 ]. Forearm HMO has been managed by one or more of the following procedures isolated excision of osteochondroma [ 6 – 12 ], acute [ 7 , 12 , 13 ], and/or gradual [ 6 , 14 – 26 ] ulnar lengthening, combined ulnar and radial lengthening [ 27 ], distal radial hemiepiphysiodesis [ 3 , 12 , 28 , 29 ], corrective radial osteotomy [ 7 , 13 , 30 ], creation of one-bone forearm [ 31 – 33 ], radial head relocation [ 8 , 10 , 22 ], reconstruction of the distal ulnar epiphysis by vascularized proximal fibula epiphysis [ 34 ] and Sauve-Kapandji procedure [ 10 ]. Nevertheless, the optimal management of HMO of the forearm is greatly disputable.…”
